The present invention relates to a snow plow for clearing roadways and other similar purposes and the prime object of the invention resides in'the provision of a struc- 5 ture mounted on the front of a wheeled frame and operated by motive power on the wheel frame so as tocause the rotation of a relatively large fan like member on a horizontal axis in front of a large vertical plate trans l versely of the front end of the frame in co- 'operation'with side heaters with vertical axes and lower corner angers on horizontal axes.

Another very'important object ofthe invention resides in the provision of an auger 15 like structure extending forwardly from and rotating with the fan like member.

A still further very important object of the invention resides in the provision of an apparatus of this nature which is simple in 20 its construction, inexpensive to manufacture, strong and durable, thoroughly efiicient and reliable in. use and operation, and otherwise well'adapted to the purpose for which it is designed. I 7

With the above and numerous other objects in view as will appear as the description proceeds, the invention residesin certain novel features of construction, and in the openings 21 in the lowercorne'rs of the plate '6 and on their forward ends have angers comcombination and arrangement of parts as will be hereinafter more fully described and claimed. 7

In the drawing: I v Figure 1 is a side elevation of the apparatus embodying the features of my invention, Figure 2 is a rear elevation thereof, Figure 3 is a front elevation thereof, Figure 4 is a top plan view thereof, Figure 5 is a perspective View of the plate with its bottom share and top bafiie,

Figure 6 is aperspective view ofone of the corner angers,

Figure 7 is a perspective view of the upper end of one'of the heaters,

Figure 8 is a perspective view of the fan like member, and p v Figure 9 is a side elevation thereof. Referring to the drawing in detail it will be'seen that the numeral 5 denotes a wheeled vehicle or frame such as a truck or the like. A rectangular plate 6 is mounted on the front end of the frame 5by means of brackets 7 'and'braces 8 or in any other suitable or preferred manner and this plate is provided at its bottom edge with a forwardly directed share 9 and across the upper end thereof with a baffle 10 comprising a relatively long curved portion a and a relatively short curved por tion 7), the juncture of these two portions a and I) being the lowest point of the baffle.

An opening 11 is provided along the vertical median dimension below the center thereof and a shaft 12 is journaled therein having on the front end in front of the plate 6- a fan like member denoted generally by the letter F and comprising a hub 14 with blades 15, preferably four in number, extending tangentially therewith and having on their front edges full length obliquely extending flanges 16 and partial length right angularly extending flanges 17 disposed oppositely to the flanges 16. V I A plurality of blades 18 are fixed to intermediate portionsof the blades and con- '-verge inwardly to; meet at a point 19 coaxially disposed with the hub 14' and the shaft 12 forwardly of the fan like member F to'provide an auger for boringinto the snow. A-pair of shafts 20 are journaled through prisinghubs 22 with curved blades 23 ext'ending in opposite direction therefrom. On the rear ends of the shaft 20 there are fixed sockets 24.

In openings 26 inthe end portions of the share 9 there are journaled the lower ends of shafts 27, the upper ends of which are journaled in brackets 28 at the upper edge of the plate 6. Beaters are mounted on these shafts 27 and each beater comprises a hub 29 fixed to the shaft 27 and having Sprockets are mounted on the rear end of'theshafts 34L.

' A sprocket 36 is mounted on the shaft 12' a H a I swingably mountedsoas to be a i i 89 thataitrmowes.tothe'sides withithe assis- 5 35. The shaft 12 may be operated in any suitable manner such as byan engine 40 hav-v 3 ring a ear 411ml the driven shaft-thereof while 7, the gear 41.
